The articles in this special issue focus on ongoing research efforts in the development, use, and evaluation of emerging hardware features and techniques to improve system security. We have seen the emergence of new hardware features to improve software security by limiting memory access within an address space, such as Intel’s memory protection keys (MPKs) and extended page table (EPT) switching, among others. Researchers have also proposed hardware-assisted roots of trust using trusted execution environments (TEEs), such as Intel’s software guard extensions (SGXs), so some questions are what the utility is of such techniques and what limitations they still face. The papers in this special issue provide guidance in these areas, which can be helpful in examining future research directions and future applications of such techniques.

新兴硬件对安全和隐私的影响

本期特刊中的文章重点关注在开发、使用和评估新兴硬件功能和技术以提高系统安全性方面正在进行的研究工作。我们已经看到了通过限制地址空间内的内存访问来提高软件安全性的新硬件功能的出现，例如 Intel 的内存保护密钥 (MPK) 和扩展页表 (EPT) 切换等。研究人员还提出了使用可信执行环境 (TEE) 的硬件辅助信任根，例如英特尔的软件保护扩展 (SGX)，因此一些问题是此类技术的效用是什么以及它们仍然面临哪些限制。本期特刊中的论文提供了这些领域的指导，有助于检验此类技术的未来研究方向和未来应用。
